On behalf of our Client from the UK, Mobilunity is looking for a AI Engineer (Part-time). The Client runs its own proprietary, self-hosted AI platform. This platform deploys open-source LLMs directly inside the client’s environment—whether on-premises or within a private AWS cloud—ensuring no data is ever shared with third-party AI services. As an AI Engineer, you will help build, enhance, and extend this AI platform to deliver tailored solutions across client projects.
What you’ll do
Deploy and serve open-source LLMs on GPU hardware with vLLM
Build RAG knowledge bases over client documents and data
Develop AI agents that query databases, send emails or create tickets, with guardrails and human approval steps
Build multi-step workflows triggered by events, schedules or user input
Integrate the platform with client CRM, ERP and helpdesk systems via APIs
Set up SSO, role-based access control, audit logging and usage policies
What you’ll need
Hands-on experience with self-hosted open-source LLMs
vLLM or a similar model serving framework
RAG pipelines: document ingestion, search, context-aware answers
AI agents and workflow automation
API integrations with business systems
AWS and GPU-based infrastructure
Understanding of data security and governance in regulated sectors (healthcare, government, education, professional services)
